Make sure there are no hoses collapsing. Make sure the radiator isn't plugged.

I flushed the entire system yesterday, took the (new) radiator out and flushed it as well. All the hoses are new and none are collapsing. I put it all back together and tested the system from cold start. Same results- coolant starts circulating at 195 degrees, fan clutch engaged, engine overheated as heat blew cold. The only other thing I can imagine to be the problem is the head gasket, but I don't want to go tearing into the engine if that isn't the issue.

If you feel it is a gasket, check compression to see if there is low compression in one of the cylinders.

A bad head gasket (or cracked head) will show up in a compression check? Sorry, I don't have experience in this.

No it won't show up in comp test. If your losing heat out of vents means air is building in heater core. Assuming you burped the system correctly you have a blown head gasket.
